Jason A. Jakob, 39, barricaded himself in a home in the 900 block of North Harvard Avenue just after 9:30 p.m. Tuesday.

When Arlington Heights police arrived, they set up a safe perimeter and also heard what were possibly gunshots inside the home. Residents near the offender’s house were evacuated. As police got closer to the home, they could see muzzle flashes and heard gunfire. Multiple shots were fired and neighbors were moved to safety down the block.

Northwest Central Dispatch 9-1-1 Center activated a Northern Illinois Police Alarm System response for an Emergency Services Team about 10:00 p.m., which called for specialist officers to coordinate a response to safely resolve the barricade situation. The unit typically includes a coordinator, assistant coordinator, an entry unit, a containment unit, marksmen, negotiations, and support services. The unit is what people commonly call a SWAT team. The NIPAS response also helps allow Arlington Heights Police Department officers to manage their routine service calls for the rest of the community while the barricade situation is managed. Police departments from Buffalo Grove, Des Plaines, Mount Prospect, Rolling Meadows, Round Lake Beach, Skokie, Streamwood and others responded to the scene. Paramedic ambulances from Arlington Heights and Palatine were placed on standby for injuries. One person was transported by ambulance to a local hospital before the offender was placed in custody.

As of 12:45 a.m. the barricade situation was unresolved and communication negotiations with the offender were being attempted. As of 3:00 a.m. a large area of neighbors, including whole families and some elderly residents were being evacuated from the area. Some residents were evacuated in a BearCat armored personnel carrier and were given shelter for the night at the Lutheran Home Chapel.
